1) 13:3

2) Same

3) 49:12

4) 95:14

5) 82:13

6) 7:8

7) 9:2

8) 29:5

9) Same

10) 10:13

Your basically dividing them by each other on a calculator

E.g. 90 ÷117 = 10/13

(10:13)

Or

20:30

20÷30=2/3

(2:3)

So, you could find the HCF of both numbers.

( highest factor of 20 & 30 is 10)

Hope this helps!

Answer:

Step-by-step explanation:

Formula

Use V = L*w* h

Givens

L = 3 cm

w = 2 1/2 cm

h = 2 1/2 cm

Solution

V = 3 * 2 1/2 * 2 1/2

Answer: V = 18 3/4 cm^3

Answer:

44 square units

Step-by-step explanation:

We can split the figure into 4 separate figures :

Area of the left triangle

Area of the right triangle

Area of the rectangle

Area of the right triangle

Area of the figure

The error is in step 2 in step 2 Susu forgot to divide 8 by 4 for finding the solution of a quadratic equation.

The name Quadratic comes from "quad" meaning square, because the variable gets squared (like x2). It is also called an "Equation of Degree 2"

Susu is solving the quadratic equation [tex]4x^2-8x-13=0[/tex] by completing the square

To apply to completing the square method we need to get x^2 alone

Susu added 13 on both sides. So step 1 is correct

When we factor out 4, we divide both terms by 4

[tex]4(\dfrac{4x^2}{4}-\dfrac{8x}{2})=13[/tex]

[tex]4(x^2-2x)=13[/tex]

Susu forgot to divide 8 by 4

So , error in step 2

We can decompose the composite figure into a triangle, a rectangle, and a semicircle in order to find the area of the composite figure.

The space filled by a flat form or the surface of an item is known as the area.

The number of unit squares that cover the surface of a closed-form is the figure's area. Square centimeters and other similar units are used to measure area.

The area of the composite figure is equal to the sum of area 1, area 2, and area 3

Area 1 - triangle

Area 2 - rectangle

Area 3  - semicircle

We can decompose the composite figure into a triangle, a rectangle, and a semicircle in order to find the area of the composite figure.

Hence option d is correct.

The mean if the scores was misread at 94 but it was 69 is 87.5

Mean is also known as average. It is mathematically represented as:

Mean  = Sum of data/Sample space

Given the following parameters

Mean = 88

Sample size = 50

Substitute

88 = Sum/50

Sum = 88(50)

Sum = 4400

If one of the scores was misread at 94 but it was 69, hence;

Sum + (94-69) = 4400
Sum + 25 = 4400
Sum = 4400 - 25
Sum = 4331
New mean = 4375/50
New mean = 87.5

Hence the mean if the scores was misread at 94 but it was 69 is 87.5

Answer:

Step-by-step explanation:

Remark

First of all, all the units must be the same. Inches is probably the best unit to use.

Second the base line at the bottom must be completed. How long is it

Givens

Left side = 48 inches

Top = 3 yards

Right side = 5 feet.

Bottom = 1 yard + top

Bottom = 1 yard + 3 yards

Bottom = 4 yards

Perimeter = 144 + 60 + 108 + 48

Perimeter = 360 Inches.

Answer

Perimeter = 360 inches

Perimeter = 360 / 12 = 30 feet     There are 12 inches in a foot

Perimeter = 360 / 36 = 10 yards.  There are 36 inches in a yard

The question does not specify the units. Probably inches would work, but if a computer is marking your answer and you get it wrong, you are going to have to try the other two answers in turn.

Answer:

No, They are complementary

Step-by-step explanation:

Supplementary is when the angles add up to 180 degrees.

Complementary is when the angles add up to 90 degrees.

Step-by-step explanation:

A

Step-by-step explanation:

As the points A, B, C and D lie on a circle, So, ABCD is a cyclic quadrilateral...

As, Sum of opp. ∠s in a cyclic quadrilateral = 180°

∴ ∠ADC + ∠ABC = 180°

=> ∠ADC + 100° = 180° => ∠ADC = 80°

Now,

Sum, of all angles in a traingle = 180°

In ΔACD, ∠CAD + ∠ADC + ∠ACD = 180°

=> ∠CAD + 80° + 40° = 180°

=> ∠CAD = 180° - 80° - 40° = 60°

As CT is tangent to the circle at the point C and CD is a chord of the circle, So

∠DCT = ∠CAD........(∠s in alternate segments are equal,,So ∠CAD = 60°)

=> ∠DCT = 60°

Answer:

See below ~

Step-by-step explanation:

∠ADC

∠DCT

Answer:

60ft^2

Step-by-step explanation:

area= 1/2(b)(h)

b for both traingles is 4

height of 1 triangle is 10 and the other is 20

total are will equal both triangles added together

area of first triangle = 1/2(10)(4)= 20ft^2

area of second triangle = 1/2(20)(4)= 40ft^2

area of the kite= 20+40= 60ft^2
